Question

Which is not the characteristic of the magnetic field set up by a straight conductor carrying current?

विकल्प

• Any conductor in which current flows behaves like a magnet.

• The direction of magnetic field is in the direction of flow of current

• The direction of magnetic field is at right angles to the direction of flow of current

• The magnetic intensity increases with the increase in magnitude of current in the conductor.

Answer 1

The direction of magnetic field is in the direction of flow of current.

Explanation:

For a straight current-carrying conductor, the magnetic field direction at any point is perpendicular to the current, not along it. The field lines are concentric circles and their strength increases with the current. The conductor also behaves like a magnet. Hence, the statement that is not a characteristic is the one saying the field is in the direction of the current.
